32-bit Disk Access (also known as FastDisk) refers to a special disk access and caching mode available in older, MS-DOS-based Microsoft Windows operating systems. It was a set of protected mode device drivers that worked together to take advantage of advanced disk I/O features in the system BIOS.
The software then tells the hard disk drive to unload its heads to prevent them from coming in contact with the platters, thus potentially preventing a head crash. [1] Many laptop vendors have implemented this technology under different names. [2] Some hard-disk drives also include this technology, needing no cooperation from the system. [3]

This can be avoided by unplugging the appliance or using a power strip and using the switch on the power strip to cut all power to the appliance." [3] Standby power used by older devices can be as high as 10–15 W per device, [4] while a modern HD LCD television may use less than 1 W in standby mode. Some appliances use no energy when turned off.
Power steering is a system for reducing a driver's effort to turn a steering wheel of a motor vehicle, by using a power source to assist steering. [1]Hydraulic or electric actuators add controlled energy to the steering mechanism, so the driver can provide less effort to turn the steered wheels when driving at typical speeds, and considerably reduce the physical effort necessary to turn the ...
Steer-by-wire without the use of a steering column was first offered in a production car with the Infiniti Q50 in 2013. [4] The system has a backup steering column separated from the steering wheel with a clutch. The clutch connects the steering wheel to the steering rack in case of failure of the electronic steering sensors or actuators. [2]
The BMW active steering system consists principally of a power-assisted rack and pinion steering gear, a double planetary gear system in the steering column, and an electric actuating motor. [ 1 ] The double planetary gear system incorporates an input sun gear connected to the driver’s steering wheel, two planetary gears, an output sun gear ...
A cross-drive steering transmission is a transmission, used in tracked vehicles to allow precise and energy-efficient steering. It consists of the following main parts: two identical single-stage planetary gearings, a differential, a hydraulic pump connected to the engine (similar to an oil pump of cars), a hydraulic motor powered by the ...
